IMPROVEMENT IN DIES FOR MAKING CHAIN -SWIVELS.

Specification forming part of Letters Patent No. 159,619, dated February9, 1875; application filed October 10, 1874,

To all whom it may concern:

Be it known that I, PHILANDER ,H. STAN- DISH, of Jefi'erson City, in thecounty of Cole and State of Missouri, have invented a new Improvement inDies for Making Chain-Swivels, of which the following is aspecification.

The invention consists in a peculiar construction of dies for themanufacture of chainswivels, as hereinafter fully described.

Figure l is a side elevation of a coil of iron on a mandrel ready forcutting up into links. Fig. 2 is a side elevation of a link-blank readyfor welding to the eye-piece. Fig. 3 is a sectional elevation of thedies for welding the link around theneck of the eye-piece, and a sideelevation of the link and eye-piece, all in position for operation. Fig.4 is a plan View of the link welded around the eye, the link and the eyeresting in the bed-dies; and Fig. 5 is a side elevation of a completeswivel.

A is the mandrel on which rod B, to form the links, is coiled. 0represents a link-blank with lapping ends, as cut from the coil, andready to be applied to the neck of the eye D, by placing one of the endsabove the neck, and the other below, to be welded around the neck of theeye-piece. E F represent t be dies,

in which the link and the eye, being so arranged, are placed forbeingwelded upon the neck, the link-blank in the circular cavity a and theeye-piece being in a straight one, I), whichcross each other, so thatwhen the linkblank and eye-piece are put in their places in the dies,and pressed together, the overlapping ends of the link-blank will befolded around the neck of the eye and welded together, and at the sametime be shaped and finished in regard to form by one or two blows of thedies. The prongs H of the eyepiece will then be heated and bent up,shaped, and welded in any approved way. The eye-piece will not be Weldedto the link on account of being cold when the link is welded around it.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The corresponding dies E F, having circular cavity a and straight one11, the two cavities crossing each other, as and for the purposespecified.
